A port of the Linux operating system kernel and assorted GNU userspace to the GameCube and Wii gaming consoles from Nintendo. Please, see http://www.gc-linux.org for additional information.
Took a bit of time to install, but once it's on it worked well. Be aware that it can't tell the difference between primary and secondary RAM, that it's no longer supported, that it's an old Debian and sometimes WiFi breaks so you need to reboot. But those are only small niggles when you consider what you get - Linux on the Wii :-)
